Is My Dog Chewing Out of Boredom or Anxiety?
Medically reviewed by Jessica Ennis, DVM, CVA — For general education — not a substitute for veterinary care.
If your dog only destroys things when you leave, that's not boredom — that's a nervous system asking for help.

Here’s the call I give most owners who bring me a chewed-up doorframe or a shredded couch cushion: it’s almost never random, and it’s almost always answerable in one week of paying attention. Boredom chewing and anxiety chewing look similar from the outside — same teeth marks, same ruined baseboards — but they come from different places, and treating one like the other wastes weeks you don’t need to lose.
What actually separates boredom chewing from anxiety chewing
Boredom chewing is a dog with energy and no outlet. It tends to show up any time the dog is under-stimulated — mid-afternoon on a rainy day, right after you sit down to work, whenever the walk gets skipped. Anxiety chewing, by contrast, is almost always tied to a trigger: you leaving the house, a thunderstorm rolling in, a new dog moving in next door. The chewing is a side effect of a nervous system that’s overloaded, not a mouth that’s under-worked.
The fastest sorting question I ask owners is simple: does it happen when you’re home, or only when you’re gone? A dog who chews the couch while you’re on the phone in the next room is telling you something different than a dog who’s fine all day and destroys the crate door the moment your car leaves the driveway.
The myth: “destructive dog” is one problem
A lot of owners come in assuming there’s one fix for chewed shoes — more toys, a bitter spray, a firmer “no.” That works for boredom. It does almost nothing for anxiety, and in my experience it can make an anxious dog worse, because now the destruction is happening and the dog is getting corrected for something it couldn’t help in the first place.
I had a case a few years back: a three-year-old fifty-pound mixed-breed named Otis, sweet dog, whose owners had gone through two rounds of “more exercise” and a rotation of chew toys before anyone asked when the chewing actually happened. It turned out Otis never touched a single thing while his owners were home — not the mail on the counter, not the shoes by the door. The destruction was 100% confined to the first twenty minutes after they left for work. That’s not a bored dog. That’s a dog in genuine distress the moment the door clicks shut, and no amount of enrichment toys was going to touch that pattern until we addressed the departure itself.
Reading the reality: five questions that sort it out
Run through these before you assume either label:
- When does it happen? Only when alone points toward anxiety. Anytime, regardless of your presence, points toward boredom.
- What gets chewed? Doors, window frames, and exit points suggest anxiety about being separated. Random household objects suggest boredom.
- Is there other behavior alongside it? Pacing, drooling, howling, or accidents in the house alongside chewing point toward anxiety. Just chewing, with a dog that’s otherwise settled, points toward boredom.
- Did more exercise change anything? If a longer walk or an extra play session cuts the chewing noticeably, that’s boredom responding to a real fix. If it doesn’t move the needle at all, look harder at anxiety.
- How did it start? A sudden onset — especially after a move, a schedule change, or a new pet — leans anxiety. A slow build as the dog matured and had less to do leans boredom.
If you’re still not confident after running through that list, our guide on Boredom vs Separation Anxiety: How to Tell the Difference walks through the same distinction with a broader behavioral lens, not just chewing.
Where nutrition and calming support genuinely fit — and where they don’t
I’ll be direct about this: no chew, treat, or supplement fixes a training gap or an unaddressed separation problem. If your dog is bored, the fix is enrichment and exercise, full stop. If your dog is anxious, the fix is a real behavior plan — often with a veterinarian or certified trainer involved — and calming support can be a genuinely useful piece of that plan, not a substitute for it.
A few ingredients have real evidence behind them for supporting a stressed nervous system, in structure/function terms rather than as a cure. Chamomile has research behind it, though a recent review notes that “for the remaining species, evidence is derived mainly from preclinical studies or traditional use,” according to a review in Biomedicines — so treat it as a support tool, not a guaranteed fix. Ashwagandha has stronger human data: a systematic review published in Cureus “analyzed multiple RCTs and concluded that ashwagandha has a moderate positive impact on stress reduction and cognitive performance.” And L-theanine has at least one notable clinical result worth knowing, even though it’s specific: a review in Molecular Psychiatry points to a study showing an effect “except for one study on psychotic anxiety (SMD = 0.54; 400 mg/day for 8 weeks)” — a human dose, not a canine one, so it’s a data point about the ingredient’s mechanism, not a dosing instruction for your dog.
None of that evidence tells you a supplement will stop separation-related chewing on its own. It tells you these are reasonable ingredients to discuss with your vet as one layer of support while you do the actual behavioral work.
The sequence I actually walk owners through
Once we’ve sorted boredom from anxiety, here’s the order I recommend, and I try not to skip steps even when owners are impatient for results:
First, address the obvious gap. If it’s boredom, that means real exercise before long alone-time stretches, a rotation of food puzzles, and fewer hours of nothing to do. This alone resolves a large share of boredom chewing within two to three weeks if you’re consistent.
Second, if it’s anxiety, start small departures. Leave for thirty seconds, come back before anything escalates, and extend gradually. This is slower than owners want it to be, and that’s normal — rushing it is the single most common reason separation work stalls out.
Third, layer in environment. A crate or safe room that’s been made genuinely comfortable, background noise to mask outside triggers, and a consistent pre-departure routine so the dog isn’t guessing.
Fourth, loop in support ingredients if appropriate, and loop in your veterinarian if the anxiety is significant — pacing, drooling, self-injury, or chewing severe enough to risk your dog swallowing material. That’s not a “wait and see” situation. If nighttime restlessness is part of the picture too, our piece on Why Does My Senior Dog Pace at Night? covers a related pattern that sometimes overlaps with anxiety-driven chewing in older dogs.
I worked with a client a couple years ago whose eight-month-old goldendoodle, about forty pounds, had started chewing the corner of the kitchen baseboard every single afternoon around four o’clock — same spot, same time, almost like clockwork. The owner assumed anxiety because it was so consistent. It wasn’t. The dog’s exercise had shifted to early mornings only, and four o’clock was simply the low point of the day, the exact moment restlessness peaked with nothing left to burn it off. We moved one walk to late afternoon, added a stuffed puzzle toy for that specific window, and the baseboard chewing stopped within ten days. The consistency of the timing had nothing to do with anxiety — it just meant we’d found her exact bored-and-restless window.
If your dog’s chewing is happening in a household with a lot going on — a new resource-guarding issue, or growling around handling that seems unrelated but might not be — it’s worth ruling out other stress sources too. Our guide on Why Does My Dog Growl When I Pet Him? A Behavior Guide is useful if chewing is showing up alongside touch sensitivity.
The bottom line
Don’t treat every chewed shoe the same way. Ask when it happens before you decide why it happens — that one question does more diagnostic work than any product on a shelf. If the chewing is confined to alone-time and comes with pacing or drooling, treat it as anxiety and get a real plan in place, ideally with your vet involved. If it happens regardless of your presence and responds to more exercise, it’s boredom, and the fix is more straightforward than owners often expect. Either way, the next right step is the same: watch for one week, write down when it happens, and let that pattern — not a guess — decide what you do next.
Frequently asked questions
Can boredom chewing turn into anxiety chewing over time?
It's possible if a bored dog's frustration compounds into broader stress, but they're typically distinct patterns. Track when the chewing happens — that timing is the clearest signal either way.
Should I stop giving my dog chew toys if I think it's anxiety, not boredom?
No — appropriate chew toys are still fine and can help redirect anxious energy, but they won't resolve the underlying separation distress on their own.
How long should I try a fix before assuming it's not working?
Give a consistent approach two to three weeks before judging it, especially for anxiety-related chewing, which tends to improve gradually rather than overnight.
